Description

Technical Field

[0001] The utility model belongs to the field of roller drive, and in particular relates to a roller drive chain self-adaptive tensioning device. Background Art

[0002] The existing tensioning device designs are all for the belt conveyor of the bucket wheel mixer reclaimer. Generally, a heavy hammer, a redirecting roller or a manual spiral tensioning device is used to solve the problems of conveyor belt slippage, deviation, insufficient conveying force, etc. The tensioning sprocket is adjusted by a screw rod. Generally, the position is adjusted during installation, but it is difficult to adjust it during later use. There are two reasons: 1. It is difficult for maintenance personnel to be in place at this position. Due to structural limitations, it is impossible to install a spacious maintenance platform; 2. The screw rod will rust due to long-term erosion by the powder and cannot be adjusted.
